If you've made some new friends down there, how about starting a co-op w/ some other moms? You guys can SHARE cooking, shopping, recipes, etc. There are moms that get together and fix meals and then share them so they have more family time, etc. This would give you more time w/ friends AND be productive at the same time.
Or.....how about teaching scrapbooking or getting involved in a scrapbooking or knitting club? Start one if there isn't one. What about a Bible study or women's book club? Again, you'd be involved w/ adults, meeting new people, developing relationships AND utilizing your gifts, talents and focusing on something you like to do.
What about starting an in-home business? There are all kinds of opportunities out there for that, regardless of whether you want to start it from the ground up or work for someone else.
Honestly, I think that being a mother is one of God's greatest gifts. Don't focus on what you don't have, focus on what you do. There are millions of women who'd love to be in your shoes. It's a PRIVILEDGE to be a mother. Enjoy every second!
Why not schedule an outing to a zoo, water park, etc EVERY week or every other week with one of your new friends. If they aren't moms and you don't think they'd enjoy something like this, then how about scheduling some time to go to lunch, coffee or something with a friend, neighbor, or family member.
Plan get togethers or card parties, or whatever for the friends you do have.
Might want to pick up a copy of PURPOSE DRIVEN LIFE by Rick Warren, too. This might help change your perspective.
